raising FF for food

[Joseph Lazzaro]

 Hi all
I'm new to this group and I would like to know how to grow ff.
I need to  be able to do this to feed my PDF (poison dart frogs).
So I would aprecciate any and all input.
I was wondering what is the best medium?
What is the proportioon of media/yeast?
What kind of yeast do you use( bakers or brewers)?
Or  do you just use comercially packaged medium?

I will be dealing  with D melanogaster and D.  hydei sturdevant.

Thank you,
J
